[0002]
[Prior art]
In recent years, with the expansion of the use of the Internet, mobile phones and PHS, which are terminals (mobile communication devices) of mobile communication systems, have been used as information terminals used in mobile environments such as car navigation systems and portable computers. The use of the Internet by connecting mobile communication devices is increasing. For example, FIG. 24 shows an in-vehicle information communication system in which the car navigation system 1 and the mobile phone 2 are combined. This system makes it possible to collect various information such as traffic information, accommodation facility information, restaurant information, etc. via the Internet in an in-vehicle environment. In addition, this system can acquire location information from sites that provide location information on the Internet, search for information around the site, or insert location information in emails and exchange location information between vehicles. To.
[0003]
On the other hand, as a wireless communication system capable of connecting to the Internet, for example, a wireless LAN system as shown in FIG. 25 is known. This wireless LAN system uses, for example, 2.4 GHz band ISM (Industrial, Scientific and Medical) band radio waves in an indoor environment such as a home, a store, an office, or an outdoor environment around a base station. It is a system that enables Internet connection.
[0004]
That is, the personal computer 11 is connected to the personal computer 11 by using the information communication device 12 that is a wireless LAN card, for example, and the information communication device 21 and the information communication device 21 installed in the access point 20 that provides the Internet connection by the wireless LAN system. It is connected to the Internet via the router 22. In the wireless LAN system, the effective radio wave range (service area) of the access point 20 is large, on the order of several hundred meters, but if the wireless communication output is of a low power type, no wireless license is required, and mobile Since there is no communication via a public line such as a mobile communication network provided by a telecommunications carrier as in the case of using a communication device, there is no communication charge for using the public line.
[0005]

The information transmission speed in the cellular phone is, for example, 9.6 kbps.
[0008]
On the other hand, since the wireless LAN system provides a service in a relatively narrow range around the access point, it is possible to increase the information transfer rate as compared with the case of using a mobile phone. In the wireless LAN system, an information transfer rate on the order of several Mbps is provided. On the other hand, the service area is limited locally, i.e. around homes, shops, offices and wireless Internet service provider base stations. Therefore, even if an information terminal used in a mobile environment is simply connectable to an information communication device for connecting to a wireless LAN system, continuity of Internet connection is not ensured.
[0009]
The Internet connection using a wireless LAN system is expected to increase in demand and increase the number of access points installed in the future due to advantages such as wireless and high speed. In particular, if a base station is installed in a house, store, office, etc. around the road, it can be used from pedestrians and cars.
[0010]
The present invention has been made in view of such circumstances. That is, the present invention selectively uses both a mobile communication system and a wireless LAN system, and can seamlessly reduce communication charges, obtain stable communication quality, and provide a high information transmission speed in Internet connection. It is an object of the present invention to provide a system, an apparatus, and a method that can be realized.

FIG. 1 is a block diagram showing the overall configuration of an in-vehicle information communication system 100 as a first embodiment of the present invention. In the in-vehicle information communication system 100 of FIG. 1, a navigation system 111 on the vehicle side 110 can be connected to the Internet using a mobile phone 112 under the control of a navigation CPU (not shown), and can also be connected to the Internet using a wireless LAN. It is also possible to connect to the Internet using an information communication device 113 that performs information communication with an access point that provides connection (hereinafter simply referred to as an access point).
[0055]
In the navigation system 111, the navigation CPU executes a navigation application and is based on a positioning result calculated by a GPS receiver (not shown) and map data (not shown) read from a storage medium such as a CD-ROM. A CPU for determining the current position by map matching and executing all functions of the navigation application. The navigation application also has a function of calculating a route between points input via an operation switch (not shown) of the navigation system 110 based on the map data.
[0056]
There are a plurality of access points (see FIG. 4). Since the flow of data transmission / reception between each access point and the navigation system 111 on the vehicle side 110 and between each access point and the communication route distribution server 152 on the server side 150 is the same, FIG. Show only. As shown in FIG. 1, the access point 130 provides an Internet connection without using a public line such as a mobile communication network. The information communication device 131 of the access point 130 has a use frequency of 2.4 GHz band (ISM band), a transmission power of 10 mW per 1 MHz, a multiple access by a direct spread spectrum system, a communication speed, as known as IEEE802.11b standard, for example. A wireless LAN system with a specification such as about 11 Mbps is provided.
[0057]
FIG. 2 shows that the navigation system 111 is in the vicinity of the route to the destination after sending the communication route distribution request to the communication route distribution server 152 after performing the route calculation from the departure point to the destination (that is, It is a figure showing the flow of the data transmission / reception until it receives distribution of the communication route map in which the access points (accessible from the route) are listed. Each access point 130 is installed in a home, a store, an office, a wireless Internet connection provider, etc., and a service area that is an effective radio wave range covers a road and can be used from a navigation system 111 mounted on a vehicle. In order to play a role as a simple roadside system, “roadside” is described in FIG.
[0058]
In FIG. 2, after the navigation system 111 executes the route calculation, the vehicle includes the calculated route information, the position information as the positioning result, and the vehicle-side ID (user ID or vehicle ID) stored in the user information storage unit 115. The information and the communication route distribution request are sent to the access point 130 on the road side via the information communication device 113 (arrow 201). On the road side, the user determination unit 132 determines the vehicle-side ID, and transmits an Internet connection permission to the car navigation system 111 only when there is an access right to the access point 130 (arrow 202). Furthermore, the access point 130 transfers the communication route distribution request and the vehicle information received from the navigation system 130 to the communication route distribution server 152 via the Internet (arrows 203 and 204).
[0059]
When the communication route distribution server 152 receives a communication route distribution request and vehicle information from a user with access rights registered in the user database 151 via the Internet, the communication route distribution server 152 receives the vehicle information and the access point database 153 based on the received vehicle information and the access point database 153. Create a communication path map. Here, the access point database 153 records the location of each access point, whether or not the Internet connection is open, and the service area. As will be described later, the communication path distribution server 152 monitors each access point in order to construct the access point database 153 and acquires information to be reflected in the access point 153.
[0060]
FIG. 4 shows the scattered state of each access point. FIG. 4 shows access points installed at home A, home B, home C, store A, store B, office A, and office B, respectively. In FIG. 4, the large and small circles indicated as the access points (for example, the circle 233b of the access point 233 in the home A) indicate the service area (radio wave effective range) of each access point. In addition, a base station that controls a part of the information communication device 131 is provided at the center of each access point (for example, the base station 233a of the access point 233). In FIG. 4, it is assumed that the office B (reference numeral 232) and the home C (reference numeral 231) do not open the Internet connection, and the other access points open the Internet connection.
[0061]
In the access point database 153, information on each access point shown in FIG. 4 is recorded. An example of the access point database 153 is shown in Table 1 below. As shown in Table 1, in the access point database 153, for each access point, the availability of the Internet, the position expressed in east longitude and north latitude, and the service area as the effective radio wave radius from the central base station Associated. As described above with reference to FIG. 4, for example, the home A opens the Internet connection, so the Internet connection is permitted. On the other hand, since the office B does not open the Internet connection, it is impossible to connect to the Internet.
[0062]
[Table 1]
[0063]
Note that the service area may not be a uniform circle due to the influence of radio wave shielding by obstacles such as buildings. In such a case, the service area information is not the effective radio wave radius, but a plurality of points on the outer periphery of the serviceable range 271 as shown in FIG. The coordinates of the point (east longitude, north latitude) may be described as service area information.
[0064]
On the other hand, in the communication route map created by the communication route distribution server 152 based on the received vehicle information and the access point database 152, the route indicated by the received route information passes through the service area. An access point is extracted. That is, the communication route map is a map showing the location of the access point and the service area that can be accessed in the process in which the vehicle side 110 on which the navigation system 111 is mounted moves from the current position to the destination. As shown in FIG. 6, when the route indicated by the received route information is as indicated by the arrow 251, the communication route map includes information on the home B, the office A, and the store B. Extracted from the access point database 153. As shown in Table 1, home C is not included in the communication route map because it cannot be connected to the Internet.
[0065]
Returning to FIG. 2, the communication path distribution server 152 on the server side 150 transfers the communication path map to the transfer source access point that performed the transfer of the arrow 203 (arrow 205, arrow 206). Furthermore, the communication path distribution server 152 sends vehicle information that is vehicle-side IDs to the extracted access points (in the example shown in FIG. 6, home B, office A, and store B) (arrow 205, 206).
[0066]
On the road side, the access point that has received the transfer of the communication route map from the server side 150 transmits the communication route map to the vehicle side 110 via the information communication device 131 (arrow 207).
[0067]
On the other hand, the access point that has received the vehicle information transfer (in the example shown in FIG. 6, home B, office A, and store B) registers the received vehicle-side ID in the user determination unit 132 and transmits the Internet from the vehicle side. It can be used to determine whether or not connection is possible. That is, registration information for determining whether or not to connect to the Internet is stored and prepared at the access point through which the vehicle side 110 is scheduled to pass. When there is no internet connection from the vehicle side 110 within a predetermined time due to a route change on the vehicle side 110 at each access point, the registered vehicle side ID is deleted by receiving the transfer from the server side 150. Internet connection may not be allowed.
[0068]
FIG. 2 shows a case where the vehicle side is permitted to connect to the Internet from the access point, and transmits / receives data to / from the server 150 via the access point. On the other hand, FIG. 3 shows the case where the access point that opens the Internet connection does not exist in the vicinity of the current position of the vehicle side 110, and when the Internet connection permission is not obtained from the access point within a predetermined time, 4 is a diagram showing a flow of data transmission / reception when the navigation system 111 on the vehicle side 110 transmits / receives data to / from the server side 150 using the mobile phone 112. FIG.
[0069]
In FIG. 3, the vehicle side 110 uses a mobile phone 112, that is, a public network including a mobile communication network provided by a telecommunications carrier, when an access point does not permit Internet connection within a predetermined time. A communication route distribution request and vehicle information are transmitted to the communication route distribution server 152 via the line and the Internet (arrows 211, 212, and 213). When the communication route distribution server 152 on the server side 150 receives the communication route distribution request and the vehicle information sent from the mobile phone 112 via the mobile communication network, that is, the communication route map, (Arrows 214, 215, 216).
Note that vehicle information is transmitted to access points extracted as being located on the route based on the route information sent from the vehicle side 110, similarly to the arrows 205 and 206 in FIG.
[0070]
FIGS. 7 to 9 show the navigation system 111 on the vehicle side 110 until the vehicle side 110 receives the communication route map after the vehicle side 110 sends the communication route distribution request as described above with reference to FIGS. 6 is a flowchart showing details of processing in an access point 130 and a communication path distribution server 152 on the server side 150.
[0071]
FIG. 7 shows processing on the vehicle side 110. When a communication route distribution request is generated on the vehicle side 110 due to the end of route calculation or the like (S11: YES), a communication route distribution request signal is generated (S12). Next, in step S13, position information and route information are acquired in the navigation system 111. Further, the vehicle side ID stored in the user information storage unit 115 is acquired (S14).
[0072]
In step S15, the communication route request signal and vehicle information (position information, route information, and vehicle side ID) obtained in steps S12 to S14 are transmitted via the information communication device 113. In step S16, it is determined whether or not an Internet connection permission signal is received within a predetermined time. When an Internet connection permission signal is obtained within a predetermined time (S16: YES), the information communication device 113 is set in a standby state for receiving and a reception of a communication path map is in a standby state (S17).
[0073]
On the other hand, if the Internet connection permission signal is not obtained within the predetermined time in step S16 and transmission through the access point 130 is not possible (S16: NO), the communication path request obtained in steps S12 to S14. The signal and vehicle information are transmitted using the mobile phone 112 (S18). The communication path distribution request and vehicle information sent in step S18 are transferred to the communication path distribution server 152 via the mobile communication network (mobile phone network) provided by the telecommunications carrier, the general telephone network, and the Internet. (S19).
[0074]
FIG. 8 is a flowchart showing processing executed in the control unit (not shown) of the roadside access point 130. First, the access point 130 determines whether or not a communication route distribution request signal and vehicle information have been received (S31). If the communication route distribution request signal and the vehicle information are received (S31: YES), the process proceeds to step S32, and the user determination unit 132 has access rights to the vehicle-side ID, for example, using information registered in advance. A determination is made whether or not. If there is no access right (S33: NO), the process returns to step S31.
[0075]
If it is determined in step S33 that there is an access right (S33: YES), the process proceeds to step S34, and an Internet connection permission signal is transmitted to the vehicle side 110. Next, in step S35, the communication route distribution request and the vehicle information are transferred to the communication route distribution server 152 via the Internet.
[0076]
FIG. 9 is a flowchart showing processing executed in the communication path distribution server 152 on the server side 150. On the server side 150, first, user registration with respect to the user database 151 is performed (S51). This user registration can be performed, for example, by manual input by an operator on the server side. Next, in step S52, it is detected whether the communication route distribution request and the vehicle information have been transferred. When the communication route distribution request and the vehicle information are transferred (S52: YES), the process proceeds to step S53, where the received vehicle-side ID and the user database 151 are collated. If it is determined by this collation that the vehicle side 110 has no access right (S54: NO), the process returns to step S52.
[0077]
If it is determined in step S54 that the vehicle side 110 has an access right (S54; YES), the process proceeds to step S55, and a communication route map is created according to the received route information. The created communication path map is sent to the transfer source access point when the communication path distribution request has been transferred via the access point (S56). On the other hand, if the communication route request has been transferred via the mobile phone network, the created communication route map is sent to the mobile phone network (S56). The vehicle-side ID is transferred to each access point extracted as a communication route map (S57).
[0078]
FIG. 10 is a flowchart showing a process executed by the control unit of the access point 130 on the road side in response to the transfer of the communication route map or the vehicle side ID by the processes in steps S56 and S57 of FIG. The access point that transferred the communication route distribution request and vehicle information received from the vehicle side 110 to the communication route distribution server 152 receives the transfer of the communication route map from the communication route distribution server 152 (S71). When the transfer of the communication route map is received, the communication route map is then transmitted to the vehicle side 110 of the transmission source of the communication route distribution request via the information communication device 131 (S72).
[0079]
On the other hand, the access point extracted in the communication route map also receives the transfer of the vehicle side ID (S73). The received vehicle ID is registered in the user determination unit 132 (S74). Next, it is determined whether or not there is an access from the vehicle side within a predetermined time (S75). If access from the vehicle side 110 having the vehicle-side ID registered in the user determination unit in the process of step S74 is within a predetermined time (S75: YES), the Internet connection permission is granted to the vehicle-side 110 that has accessed. (S76). When there is no access from the vehicle side having the vehicle side ID registered by the process of step S74 in the user determination unit within the predetermined time (S75: NO), the vehicle side ID registered in the user determination unit 132 by the process of step S74 Is erased (S77). Internet access is not permitted for access from the vehicle side in which the vehicle-side ID has been deleted from the user determination unit 132 by the processing in step S77 (S78).
[0080]
FIG. 11 is a diagram showing a flow of data transmission / reception when information stored in the access point database 153 is monitored by accessing each access point in the communication path distribution server 152 on the server side 150. In addition, this monitoring shall be regularly performed with respect to all the access points. FIG. 11 shows only whether or not Internet connection is possible as an example of the contents to be monitored, but it is assumed that other contents, such as location information and service area, are similarly queried.
[0081]
In FIG. 11, the communication path distribution server 152 on the server side 150 sends an inquiry as to whether or not Internet connection is possible to the access point, for example, the home A via the Internet (arrows 221 and 222).
[0082]
When an inquiry is received from the communication path distribution server 152, the access point (home A) on the road side sends a response of permission to the communication path distribution server 152 via the Internet when the Internet connection is permitted. (Arrows 223 and 224).
[0083]
FIG. 12 is a flowchart showing the monitoring process executed in the communication path distribution server 152 on the server side 150 described above with reference to FIG. In FIG. 12, first, periodic monitoring of each access point is executed by the communication path distribution server 152 (S61). Next, the communication path distribution server 152 collects information on whether to open the Internet connection, location information, and service area for each access point (S62). Using the collected information, the access point database 153 is constructed by the communication path distribution server 152 as shown in Table 1 (S63).
[0084]
FIG. 13 shows the navigation system 111 when the Internet connection is performed by the activation of a browser (information browsing software) or a mailer in the navigation system 111 on the vehicle side 110 that has received the distribution of the communication accounting map from the communication path distribution server 152. It is a figure showing the flow of data transmission / reception between the Internet.
[0085]
As shown in FIG. 13, the vehicle side 110 uses the current position and the communication path map to determine whether the current position is within the service area in the communication path map. In the service area of a certain access point, Internet connection is made via a roadside access point (arrows 231 and 232). In this case, the mobile phone network and the general telephone network by the telecommunications carrier are not used. On the other hand, outside the access point service area, the navigation system 111 uses the mobile phone 112 to connect to the Internet via the mobile phone network and the general telephone network (arrows 241 and 242).
[0086]
FIG. 14 is a flowchart showing details of processing executed in the navigation CPU of the navigation system 111 when the navigation system 111 receives the communication route map and connects to the Internet by starting up a browser or a mailer. In the navigation system 111, when a communication route map is received via the information communication device 113 or the mobile phone 112 (S101), the received communication route map is stored in the communication route storage unit 114 (FIG. 1) (S202). .
[0087]
In step S103, when the Internet connection is generated by the activation of the browser or the mailer in the navigation system 111, the communication route map stored in the communication route storage unit 114 is read, and the current position of the vehicle and each access in the communication route map are read. Comparison based on point information (location and service area) is performed (S104).
[0088]
As a result, when the current position is within the service area of the access point in the communication path map (S105: YES), the Internet connection via the access point whose current position is located within the service area is established. Performed (S106). Next, the process proceeds to step S107, where it is determined whether or not the internet connection is terminated. If the internet connection is not terminated (S107: NO), the process returns to step S104. In other words, when the Internet connection is continued, the comparison between the current position and the communication route map is repeatedly executed (S104), so that the current position is always in the service area of each access point in the communication route map. Internet connection is made through an access point in the service area. If the Internet connection is terminated due to termination of the browser or the like (S107: YES), the processing is terminated.
[0089]
On the other hand, when the current position is not located in the service area of any access point in the communication route map in step S105 (S105: NO), the Internet connection is made via the mobile phone 112 ( S108). Next, the process proceeds to step S109, where it is determined whether or not the Internet connection has ended. If the Internet connection has not ended (S109: NO), the process returns to step S104. If the Internet connection is terminated due to termination of the browser or the like (S109: YES), the processing ends.
[0090]
With the processing shown in FIG. 14 described above, the navigation system 111 can access points when browsing the Internet site using a browser, sending / receiving emails, and other Internet connections during travel on the route from the departure point to the destination. In the service area, the Internet connection is made preferentially through the access point at a high data transfer rate and without going through the public line, and the mobile phone is connected outside the service area of the access point. In the example of the route 251 described with reference to FIG. 6, the vehicle side 110 is in the service area of the access point 255 (home B), the access point 256 (office A), and the access point 257 (store B). Internet connection is made via an access point, and at other locations, internet connection is made via a mobile phone network using a mobile phone. Therefore, an increase in information transmission speed and a stable communication quality in a mobile environment can be maintained, a communication fee can be reduced, and a seamless Internet connection can be performed.
[0091]
The navigation CPU in the navigation system 111 serves as a part of the information communication device 113 in the service area of the accessible access point included in the communication route map based on the current position and the acquired communication route map. A directional antenna (not shown) is controlled. FIG. 15 shows a state of antenna directivity control by the navigation system 111. As shown in FIG. 15, in the navigation system 111, the position P on the vehicle side 110 1 And access point position P A And the direction in which the directivity of the antenna is directed is determined, and the determined direction, ie P 1 → P A Control is performed so that the directionality of the directional antenna is directed to the direction.
[0092]
In the directional antenna on the vehicle side 110, directivity control with respect to the access point base station is performed, so that only radio waves traveling straight from the access point base station are received and affected by multipath fading. Receiving radio waves is avoided and further improvement in communication quality is achieved.
[0093]
As shown in FIG. 16, each access point periodically transmits a beacon for determining a radio wave reception level on the vehicle side 110. As shown in FIG. 16, as one of the functions of the navigation CPU in the navigation system 111, a reception level determination unit 111a that acquires the reception level of the beacon detected by the information communication device 113 and determines the reception level is configured. Is done. The reception level determination unit 111a compares the acquired reception level with a predetermined reception level. Further, the Internet connection is controlled by the navigation CPU based on the determination result. Details of the control of the Internet connection in this case are shown in FIG.
[0094]
As shown in FIG. 17, in step S151, a beacon periodically transmitted from an access point is received by the information communication device 113 within the service area of the access point in the communication route map, and the reception level of the beacon is It is detected (S151). The reception level determination unit 111a performs determination by comparing the reception level with a predetermined level representing a level at which stable communication is possible (S152). As a result, when the reception level is lower than the predetermined level (S163: YES), the Internet connection is made using a mobile phone (S154). On the other hand, when the reception level exceeds the predetermined level (S153: NO), the Internet connection via the access point using the information communication device 113 is made. After steps S154 and S155, the process returns to step S151, and the determination of the reception level is repeated.
[0095]
FIG. 18 is a block diagram showing the overall configuration of an in-vehicle information communication system 300 as the second embodiment of the present invention. As shown in FIG. 18, the in-vehicle information communication system 300 is an Internet connection system operated by an Internet connection company between the access point 130 and the Internet with respect to the in-vehicle information communication system 100 shown in FIG. 1. 310 is interposed. Further, in the in-vehicle information communication system 300, for example, an advertisement input device 320, which is a personal computer, is connected to the Internet.
[0096]
In FIG. 18, only one access point 130 is shown, but it is assumed that a plurality of access points are connected to the Internet connection system 310. The access point 130 and the Internet connection system 310 are always connected by a wired system such as a telephone network, a CATV network, and a dedicated line.
[0097]
The Internet connection system 310 provides users with general functions as an Internet connection system such as user management, connection charge management, domain name server, web server, and mail server, and further includes an advertisement distribution server 311. , An advertisement provider database 312, and an advertisement database 313.
[0098]
The advertisement input device 320 is a device mainly used by advertisement providers such as stores, hotels, companies, and local governments, and can be connected to the advertisement distribution server 311 via the Internet. The data input by the advertisement provider via the advertisement input device 320 is the advertisement provider name, advertisement information such as product information, company information, accommodation information, and tourism information, and an advertisement provision area, that is, an advertisement provision target. Access point name. Data input by the advertisement input device 320 is transferred from the advertisement input device 320 to the advertisement distribution server 311, and is registered in the advertisement database 313 after user authentication in the advertisement distribution server 311.
[0099]
Table 2 below shows the configuration of the advertisement database 313. As shown in Table 2, in the advertisement database 313, an advertisement provider name and advertisement information are associated with an access point name as information for specifying an access point. The access point name may be the network address or URL of the access point instead of or in addition to the unique name of the store A or the like. Further, the number of advertisements provided is associated with the name of the advertisement provider and the advertisement information. For example, referring to the column of access point name home A in Table 2, the number of times that advertisement information of store A is distributed is 30 times, and the number of times that advertisement information of company A is distributed is 20 times. I can know.
[0100]
[Table 2]
[0101]
The operations of the advertisement distribution server 311 and the advertisement input device 320 in the in-vehicle information communication system 300 are shown in FIGS. FIG. 19 is a flowchart showing processing in the advertisement input device 320. As illustrated in FIG. 19, in the advertisement input device 320, an advertisement provider company name is input via the user interface of the advertisement input device 320 in step S <b> 401. Next, advertisement information is input (S402), and an access point name is input as an advertisement providing area (S403). In step S404, the advertisement provider company name, advertisement information, and advertisement provision area input in steps S401 to S403 are transmitted to the advertisement distribution server 311 via the Internet. The advertisement information is input as data such as character information, audio data, still image data, and moving image data.
[0102]
FIG. 20 is a flowchart illustrating processing executed by the advertisement distribution server 311 upon receiving the transfer of advertisement information from the advertisement input device 320. In the advertisement distribution server 311, the advertisement provider is registered in advance in the advertisement provider database 312 (S 431). Next, when there is data transfer from the advertisement input device 320, the received advertisement provider name is compared with the advertisement provider database 312. As a result, if the data transfer from the advertisement input device 320 is from the advertisement provider registered in the advertisement provider database 312 (S432: YES), the received advertisement information is registered in the advertisement database 313. (S433). If the transfer is from an advertisement provider that is not registered (S432: NO), registration in the advertisement database 313 is not performed, and a standby state is waited for the next transfer.
[0103]
FIG. 21 shows that in the navigation system 111 on the vehicle side 110, when the Internet connection is made via the access point 130 by the activation of the browser or the mailer, the advertisement distribution server 311 transfers from the Internet side to the vehicle side 110. It is a flowchart showing the process which adds advertisement information to the data to be performed. The advertisement distribution server 311 monitors the Internet connection via the access point 130 (S451). When the Internet connection via the access point is detected (S451: YES), advertisement information associated with the access point relaying the Internet connection from the vehicle side 110 is read from the advertisement database 313 (S452). At this time, the number of advertisements provided in the advertisement database 313 associated with the access point relaying the Internet connection from the vehicle side 110 is counted up, and the advertisement database 313 is updated. The read advertisement information is added to the data transferred to the vehicle side 110 that has been connected to the Internet in step S451 (S453).
[0104]
For example, if the access point relaying the Internet connection on the vehicle side 110 is the home A in Table 2, the advertisements of the store A, the hotel A, and the company A, which are advertisement providers, associated with the home A as the access point. The number of offers is counted up. That is, the number of times the advertisement information is distributed to the vehicle side is counted for each advertisement provider.
[0105]
The advertisement information added by the advertisement distribution server 311 is received by the navigation CPU of the navigation system 111 together with data from the Internet. As shown in FIG. 22, under the control of the navigation CPU, the contents of the data received from the Internet excluding the advertisement information are displayed on the portion of the Internet display screen 117a on the display screen 117 of the navigation system 111. Are displayed on the advertisement display screen 117b. If the advertisement information is audio data, the audio information is read out by an audio reproduction unit (not shown) of the navigation system 111 (reference numeral 117c).
